Geography · Climatology
Consider the following statements regarding insolation variation: Statement 1: The amount of insolation received at a location varies with latitude. Statement 2: The angle of incidence of solar radiation changes with latitude, affecting the concentration of solar energy per unit area. Statement 3: The thickness of the atmosphere through which sunlight passes increases at higher latitudes, leading to greater scattering and absorption of solar radiation. Which one of the following interpretations is correct?
- 1Statement 1 is primarily explained by Statement 2, while Statement 3 plays a secondary role in higher latitudes.✓
- 2Statement 1 is explained by both Statements 2 and 3, with Statement 2 being more significant in tropical regions.
- 3Statement 1 is independent of Statements 2 and 3, as local factors like altitude and cloud cover have a greater impact.
- 4Statement 1 is explained only by Statement 3, while Statement 2 is unrelated to insolation variation.
Correct answer
Statement 1 is primarily explained by Statement 2, while Statement 3 plays a secondary role in higher latitudes.
